WINTER may seem like a time to relax for fruit growers, but the Goulburn Murray Valley Fruit Fly Area Wide Management Program continues to educate the community, industry, and government on controlling Queensland fruit fly (Qfly). With workshops and community engagements, the program aims to reduce Qfly populations before spring.
Program coordinator Ross Abberfield emphasises that not all fruit flies die in winter. Many adult flies survive by taking refuge in evergreen plants near homes and buildings where temperatures are milder. One significant contribution to their survival is the unmanaged leftover fruit on late fruiting plants. Abberfield advises post-harvest fruit removal to reduce orchard diseases and control other pests.
Managing Qfly through winter
Fruit Fly researcher Andrew Jessup highlights that adult flies are the main concern during winter as eggs and larvae usually die off by June. He recommends using food-based traps and baits, especially during warmer parts of the day, to control any active adult flies seeking food. Proper management now can prevent a large Qfly population later.
Removing unwanted fruit trees
Home gardeners and commercial growers should focus on removing unwanted and unmanaged fruit trees. This includes checking for fruiting weeds, hedge plants, and trees with late-hanging fruit. Community support has already led to the removal of over 115,000 unwanted fruit trees. If you see unwanted plants or rogue trees, report them to your local Council for removal.
Advice to home gardeners and commercial growers
Winter trapping with protein-based traps in sunny spots of evergreen trees is also effective. Lemon trees are particularly favoured by Qfly for nesting. For residents in Greater Shepparton, Moira Shire, Campaspe Shire, or Strathbogie Shire, free removal of unwanted fruit trees is available through the program.
Steps for Home Gardeners and Growers:
- Remove Unwanted Trees: Identify and remove unmanaged fruit trees and weeds.
- Use Protein-Based Traps: Place traps in warm, sunny spots in evergreen trees.
- Regular Maintenance: Continuously pick up fallen fruit and harvest late-hanging fruit.
- Report Rogue Trees: Inform local Council about unwanted trees for removal.
